Background: Bubble electrospinning has been commercially used for mass-production of various nanofibers, but its application to fabrication of nanofiber yarns is little studied. We find there is a great potential in this direction.
Objective: This paper aims at a survey on bubble electrospinning with an emphasis on new technologies for fabrication of fascinated nanofiber yarns by the bubble electrospinning.
Method: The paper begins with the mechanism of the bubble electrospinning to introduce how to produce fascinated nanofiber yarns experimentally, then the industrialization of fascinated nanofiber yarns is illustrated.
Results: The bubble electrospinning is extremely suitable for fabrication of fascinated nanofiber yarns with hierarchical structure, and the hierarchy can be designed biomimetically according to some natural fibers.
Conclusion: This paper sheds a light on both experimental study and industrial applications of fascinated nanofiber yarns.
